Working at Dairy Queen when I was a teen. I was cleaning the soft serve machine and forgot to depressurize and drain the machine before i opened the front up. As soon as I loosened the last bolt it exploded gallons of chocolate and vanilla soft serve ice cream. In an instant, the entire mall food court was sprayed in a fine mist of soft serve. Once I wiped the ice cream from my eyes and realized what just happened, I looked around and there was a perfect outline of my silhouette on the wall behind me.
